True gigantism is thought to have arisen late in mysticete history, with species exceeding 10 m unknown prior to 8 Ma. This view is challenged by new fossils from Seymour Island (Isla Marambio), Antarctica, which suggest that enormous whales once roamed the Southern Ocean during the Late Eocene (<span class=\"italic\">c</span>. 34 Ma). The new material hints at an unknown species of the archaic mysticete <span class=\"italic\">Llanocetus</span> with a total body length of up to 12 m. The latter is comparable to that of extant Omura's whales (<span class=\"italic\">Balaenoptera omurai</span> Wada <span class=\"italic\">et al</span>. 2003), and suggests that gigantism has been a re-occurring feature of mysticetes since their very origin. Functional analysis including sharpness and dental wear implies an at least partly raptorial feeding strategy, starkly contrasting with the filtering habit of living whales. The new material markedly expands the size range of archaic mysticetes, and demonstrates that whales achieved considerable disparity shortly after their origin.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Gigantic mysticete predators roamed the Eocene Southern Ocean","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Antarctica; baleen whale; Llanocetus; Palaeogene; raptorial; suctionfeeding","OtherDescriptors":null,"Notes":null,"AnaPub":2019,"MonPub":null,"DateUpdate":"2019-05-29","DateCreate":"2019-05-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000463086400007","VABBcode":null,"OpenAcc":0,"DOI":"10.1017/S095410201800055X"},"refs":null,"anarec":{"AnaID":311371,"PubliDate":2019,"Pagination":"98-104","XtraPublOfAnaID":null,"ISBN":null,"Volume":"31","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45043,"SerRR":"Antarctic Science.
